FLUIDISTOR – GAS FLOWMETER GD 300 EX WITH intermediate flange / WAFER

Installation length of 65 mm
easy replacement of 99 % built-in flowmeters
Simple and space-saving installation between ISO and ASME flange
Oscillating measurement principle, without moving parts – no wear parts
High accuracy (±1,5 % of true value)
Measuring range of 1:100
Option: ball valve (blocking valve) in order to removal or installation of the platinum wire sensor without emptying the system

The wafer process connection is the lightest body version for mounting between pipe flanges.

The device is installed between the pipe flanges and tightened to its place with the bolts of the flanges.
The installation length of the gas flowmeter GD 300 Ex with the wafer process connection is 65 mm regardless of the nominal width (DN). Additionally the wafer process connection is independent of the used flange type.

Therefore a simple and space-saving installation between either ISO or ASME flanges can be realised.
